Midwinter is approaching, and Tenny can't wait to spend their first Christmas with her babies. However, compared to spending a good time with their family, the little guys seem to be more interested in desperately searching for gifts. In order to let the children experience the true meaning of Christmas, Tenny and her husband planned a special Christmas show of Cute Dogs, singing Christmas carols to the family and inviting the magical Santa Claus and his reindeer!
